Tensile tests and bending tests (to ensure the joint is stronger than the bar itself).
) typically ranging up to 50 mm, or as specified by local building regulations.
A vital section of the standard addresses the verification of weld integrity. Because surface ribs prevent standard non-destructive testing (NDT) methods like ultrasonic inspection from being fully reliable, EN ISO 17660-1 heavily relies on destructive testing. ISO 17660-2 - iTeh Standards
Welders and welding operators must be specifically certified for rebar welding. This requires passing practical tests that simulate the unique geometry and material properties of reinforcing steel. en iso 17660-1 pdf
EN ISO 17660-1 specifies technical requirements for welding load-bearing reinforcing steel in workshops and on-site, excluding non-load-bearing joints. It outlines essential standards for materials, welding processes, and qualification of personnel, necessitating a Welding Procedure Specification (WPS). Purchase the official standard from the ISO Store .
The EN ISO 17660-1 document is not just a suggestion—it is a technical code. The PDF typically runs 20–30 pages and includes:
The welded joint must demonstrate that its tensile strength matches or exceeds the specified characteristic yield strength of the parent reinforcing bar.
The standard mandates that only qualified welders or welding operators who hold valid test certificates according to relevant standards (like ISO 9606-1 or specific reinforcement welding qualifications) are allowed to perform the work. Furthermore, a qualified must oversee the entire operation. Why Accessing the Official Standard is Essential The official PDF is fully searchable

: It specifies requirements for weldable and stainless reinforcing steels used in both workshops and on-site. Personnel Qualification : It mandates that both the welder and the welding coordinator possess a high level of skill and job knowledge. Quality Assurance
Contractors cannot simply begin welding reinforcement on a whim. Under EN ISO 17660-1, all load-bearing welding must be executed based on a written Welding Procedure Specification (WPS). This document defines parameters like current, voltage, travel speed, preheating temperatures, and filler material types. 4. Qualification and Testing
